Spiral Drill Bit DeWalt DT20602-QZ 3 mm, hex shank, 72 mm length

DeWalt DT20602-QZ is a 3 mm spiral drill bit with a hex shank and a total length of 72 mm, intended for use with drills and impact drivers that accept hexagonal shanks. The compact diameter and overall length make this bit suitable for precision drilling and work in confined spaces. The spiral flute design facilitates chip removal and steady penetration in a range of common materials.

Advantages

The hex shank provides reliable engagement in chucks and quick-change holders, reducing slippage during use. The 3 mm diameter offers high positional accuracy for small holes, while the 72 mm overall length balances reach and rigidity. The spiral flute geometry promotes efficient chip evacuation, which helps maintain drilling speed and reduces binding. Constructed to meet general-purpose requirements, the bit is compatible with standard rotary and impact drilling applications.

Suitable for

• Precision drilling of small diameter holes in wood, plastics and soft metals
• Working in tight or confined spaces where a compact bit is needed
• Use with quick-change hex holders and standard drill chucks
• General maintenance, assembly and fitting tasks requiring repeatable small holes

Key specifications

• Tip diameter: 3 mm
• Shank type: hexagonal
• Overall length: 72 mm
• Flute type: spiral (twist)
• Intended drive: rotary and impact drivers that accept hex shanks

How to use

Install the hex shank securely into the drill chuck or quick-change holder, ensuring the bit is properly seated and locked. Select an appropriate drill speed and feed pressure for the material being drilled; lower speeds and steady pressure are recommended for hard plastics and metals, while higher speeds may be acceptable for softer woods. Retract the bit periodically when drilling deeper holes to clear chips and maintain cutting efficiency. After use, clean chips from the spiral flutes and store the bit protected from corrosion and mechanical damage.

Usage recommendations

For accurate results, use appropriate pilot markings and clamp the workpiece to prevent movement. When drilling metals, apply cutting fluid or lubricant as required to reduce heat and wear. Replace the bit if signs of wear or deformation appear to maintain hole quality and safe operation.
